I think GlusterFS usage in pacemaker clusters is not so common (eg, I don't know if it is supported at all in RH EL clusters).

It is not so clear to me if you configured GlusterFS outside of pacemaker or not: in fact through a quick search I found both types of attempts around...

Probably inside the bugzilla you should precisely outline your configuration and in case of embedding GlusterFS as a resource, what is you pacemaker configuration, so how your configured your resources/clones (eg ocf:glusterfs:glusterd, ocf:glusterfs:volume, ecc..), so that it easily reproducible

Personally I never used GlusterFS with Pacemaker
